Complete Set of Commercial Plans

Building plans are a graphical representation of what a proposed building will look like after construction. They are typically used by builders and contractors to construct buildings and can include site plans, foundation plans, floor plans, and building elevations and many others. Anyone who is constructing a new building, adding on to an existing building, remodeling an existing building, changing the occupancy and use of an existing building or space will need to submit building plans for review.

For buildings over 5,000 square feet, state law requires that structural, mechanical, electrical and plumbing plans be sealed by a Texas Professional Engineer. This requirement applies even if the tenant or work area is less than 5,000 sf, but the building itself is over 5,000 sf.

Helpful Information

The rules for engaging a registered architect are defined by The Texas Board of Architectural Plans Examiners.

The rules for engaging a registered engineer are defined by The Texas Board of Professional Engineers.

Plans that are not required to be drawn by licensed professionals may be drawn by the applicant, a designer, draftsman or any other qualified person.

Plans should be drawn to scale. A typical building plan scale is 1/8 inch equals 1 foot.

Plans should be sizes to allow all information to be easily read. A typical plan sheet size is 24 inches tall by 36 inches wide but larger and smaller sizes are acceptable.
